Founded in 1900, the Labour Party overtook the Liberal Party as the main opposition to the Conservative Party in the early 1920s, forming minority governments under Ramsay MacDonald in 1924 and from 1929 to 1931. Labour later served in the wartime coalition from 1940 to 1945, after which it formed a majority government under Clement Attlee. Labour was also in government from 1964 to 1970 under Harold Wilson and from 1974 to 1979, first under Wilson and then James Callaghan. The Labour Party was last in government from 1997 to 2010 under Tony Blair and Gordon Brown, beginning with a landslide majority of 179, reduced to 167 in 2001 and 66 in 2005. Having won 232 seats in the 2015 general election, the party is the Official Opposition in the Parliament of the United Kingdom. Labour is the largest party in the Welsh Assembly, the third largest party in the Scottish Parliament and has twenty MEPs in the European Parliament, sitting in the Socialists and Democrats Group. The party also organises in Northern Ireland, but does not contest elections to the Northern Ireland Assembly. The Labour Party is a full member of the Party of European Socialists and Progressive Alliance, and holds observer status in the Socialist International. In September 2015, Jeremy Corbyn was elected Leader of the Labour Party. (en)

The Labour Party is a democratic socialist party. It believes that by the strength of our common endeavour we achieve more than we achieve alone, so as to create for each of us the means to realise our true potential and for all of us a community in which power, wealth and opportunity are in the hands of the many, not the few, where the rights we enjoy reflect the duties we owe, and where we live together, freely, in a spirit of solidarity, tolerance and respect.
